IMHO if Ruger continues to produce the #1 variations such as the RSI, 1AH, 1V, and 1S in interesting calibers they will continue to sell out.

These variations were never in alot of different cartridges, example for years the RSI was only available in .243, 7x57, .270 and 30.06.

What's not to like about a RSI in 25-3000, 6.5x55, 7-08, 30-30, 338 Fed 348, 35 Rem , 358 Win , etc:
